Seems to be working fine on http://playground.xwiki.org/xwiki/bin/view/Main/Aaron
Maybe there was a problem specifically on 6.2RC1 (BTW better use some final releases…:)).
I’d recommend 6.4.5 for the 6.x cycle.
Thanks

Page syntax is XWiki 2.1 and the velocity is wrapped. Sorry, I didn't include the full

{{velocity}}
#set($getURL = "https://www.example.com/api/example.mhtml?param=123")
$getURL
#set($content = $xwiki.getURLContent($getURL))
$content
{{/velocity}}
If I set $getURL to "https://google.com", it prints $content to the page. With
my API URL, I get nothing but the link in $getURL. But if I follow that link, I get the
expected XML page from the API, so I know the URL is working correctly.
I figured it was because $content is XML from the API, and HTML from google, but
using $services.xml.parse on the response doesn't work either.
The strange part is that this is code that I haven't touched in quite some time, and
used to be working. The full code parses the XML response and saves various elements to an
HTML table on the page - but it doesn't appear to be getting that far.

Any ideas?
What is the syntax of your page? Are you sure it’s XWiki Syntax 2.0+ and you’re wrapping
the velocity content with the {{velocity}} macro for example (you didn’t show it in your
example).
$response is still there
Thanks

New subject: [xwiki-users] XML with getURLContent()
I've updated that playground page with the actual URL of the API I'm using
- you'll see that the page comes back blank, but if you follow the link in
the browser, you get a page full of XML. So there must be something about
the data that the API is returning that XWiki doesn't like?
Agreed on using final releases - a full upgrade to 7.x is actually planned
soon. If I remember correctly, we got stuck on RC1 during the last
production upgrade cycle because there was some feature in 6.2 that we
really needed but the final release was still a few weeks out by our
deadline so we rolled the dice. Fortunately we haven't run into many issues
- which is probably why we're running behind on the upgrade :)

This is because you’ve used HTTPS. If you use HTTP it works fine.
ATM getURLContent() doesn’t support HTTPS.

New subject: [xwiki-users] XML with getURLContent()
Yep, that's it. Changed it to HTTP and it worked fine. I must have changed
the URL in otherwise working code at some point and forgotten about it.
Oddly, using https://google.com still works for me, but not using https
with my actual API URL. Either way, good to know that HTTPS isn't supported.
Thanks much for the help,
aaron
